That restriction is totally separate from any other limitations on running the engine at takeoff/miltary power at low airspeed. If the engine had a separate restriction on for example time at takeoff power that still applied over and above the 10 minute WEP restriction.

Running MW50 did not magically give the engine the ability to disregard its normal restrictions its cooling properties were a side effect and minimal. People seem to think if MW50 was permitted for 10 minutes then the engine should last 10 minutes regardless of how you mistreat it. That is just silly.


Gratuitous MW50 operation instructions in German :

Let me translate that first sentence, the most important of them all, for jermin.

"What is MW-50 operation?
MW-50 operation means: Temporary extraction of emergency power for the purpose of hoirzontal and climb speed increase, allowed by boost pressure increase to 1,7ata and simultaneous injection of MW-50."

So, as I told you before, it is not meant for the pilot to give him an edge in zoom climbing or general fighting, but to increase his speed to get out of trouble.
